Abstract: The number of publications is the first criteria for assessing a researcher output. However, the main measurement for author productivity is the number of citations, and citations are typically related to the paper's visibility. In this paper, the relationship between article visibility and the number of citations is investigated. A case study of two researchers who are using publication marketing tools confirmed that the article visibility will greatly improve the citation impact. Some strategies to make the publications available to a larger audience have been presented at the end of this paper.

Abstract: Due to the effect of citation impact on The Higher Education (THE) world university ranking system, most of the researchers are looking for some helpful techniques to increase their citation record. This paper by reviewing the relevant articles extracts 33 different ways for increasing the citations possibilities. The results show that the article visibility has tended to receive more download and citations. This is probably the first study to collect over 30 different ways to improve the citation record. Further study is needed to explore and expand these techniques in specific fields of study in order to make the results more precisely.

Abstract: Measuring the number of papers which are published each year, publication productivity is the factor which shows the reputation of universities and countries. However, the effect of growing economy and using internet on the publication productivity in Asian countries has not been discovered yet. The present research is going to figure out the publication productivity among the elite universities in Asian countries and also ten top universities around the world in the last twenty years (from 1993 to 2012). Furthermore, the current research is aimed to study the relationship among publication, gross domestic product (GDP) and internet usage. It is worth to mention that the publication of the top Ten Malaysian Universities was regarded for the similar period of time. To get the exact numbers of documents like papers, conference articles, review papers and letters which are published by the universities in the last twenty years, the writer of the same paper used the Science Direct database. Moreover, the data for GDP and the number of internet usage was collected through the World Bank database (World Data Bank).To compare all kinds of publications,one-way ANOVA was used and to investigate the impact of economic growth and internet usage on publication productivity, multiple regression analysis was applied.The results showed that the rate of publication growth was 1.9, 20.9, and 65.5 % in top universities in the world, ASEAN countries and Malaysia, respectively.The results also showed that there was a positive and significant correlation between GDP and the number of internet users with the number of publications in ASEAN and Malaysian universities. Internet usage had much more influence in comparison with the GDP in predicting the number of publications among these groups except for top ten Malaysian universities from 2003 to 2012. In summary, publication trends in top ten Malaysian and ASEAN universities are promising. However, policy makers and science managers should spend much more percentage of their GDP on Internet facilities and research studies that their outputs lead to more rapid economic growth and internet usage.

Abstract: Clinical isolates were collected from north temperate and southern tropical regions in Iran. Primers have been designed based on P. vivax sequence (ctg_6991) which amplified a fragment of about 1044 bp with no size variation. Direct sequencing of PCR products was used to determine polymorphism and further bioinformatics analysis in P. vivax sexual stage antigen, pvwarp.Amplified pvwarp gene showed 886 bp in size, with no intron. BLAST analysis showed a similarity of 98–100% to P. vivax Sal-I strain; however, Iranian isolates had 2 bp mismatches in 247 and 531 positions that were non-synonymous substitution [T (ACT) to A (GCT) and R (AGA) to S (AGT)] in comparison with the Sal-I sequence.This study presents the first large-scale survey on pvwarp polymorphism in the world, which provides baseline data for developing WARP-based TBV against both temperate and tropical P. vivax isolates.Plasmodium vivax is one of the two most prevalent species of human malaria parasites that occurs throughout the tropics, except in western and central sub-Saharan Africa, where the absence of Duffy factor on the surface of red blood cells largely protects the local populations [1]. In addition, recent studies have suggested that vivax malaria can become lethal in a similar way to severe falciparum malaria [2-5]. To date, the anti-malarial treatment and the vector control measures have not had a significant impact on the transmission of malaria from humans to mosquitoes. Therefore, vaccine-targeting antigens expressed on the surface of the sexual stages of malaria parasites, such as gametocytes, gametes, zygotes and ookinetes, are being considered for the development of a transmission-blocking vaccine (TBV) [6-8], a promising strategy for malaria control. The parasite has to undergo a complex development programme inside the mosquito from gametocyte to sporozoite [9]. So far, several studies have focused on the identification and characterization of TBV targets [10-14]. One of the TBV targ

Abstract: The PvWARP was expressed in Escherichia coli BL21 using the pET-23a vector and was purified using Ni-NTA affinity chromatography from a soluble fraction. Polyclonal antibody was raised against rPvWARP and transmission blocking activity was carried out in an Anopheles stephensi-P. vivax model.Expression of full length of PvWARP (minus signal peptide) expression showed a 35-kDa protein. The purified protein was recognized by mouse polyclonal antibody directed against rPvWARP. Sera from the animals displayed significantly a blocking activity in the membrane feeding assay of An. stephensi mysorensis.This is the first report on P. vivax WARP expression in E. coli that provides an essential base for development of the malaria TBV against P. vivax. This may greatly assist in malaria elimination, especially in the oriental corner of WHO Eastern Mediterranean Regional Office (WHO/EMRO) including Afghanistan, Iran and Pakistan.Plasmodium vivax is responsible for 25-40% of annual cases of malaria especially in parts of Latin America and Asia [1]. Drug resistance in P. vivax is spreading and vivax malaria has been considered lethal in a similar way to severe falciparum malaria [1-3], challenging the concept that P. vivax malaria as 'benign' [4]. Therefore, the development of new control strategies such as a safe and an effective malaria vaccine is expected to play an important role in controlling P. vivax malaria [5].Based on the life cycle stages, malaria vaccines have focused on candidate target antigens on asexual and sexual stages of the parasite [6]. A transmission-blocking vaccine (TBV) targeting the parasite's sexual stages aims at interfering and/or blocking pathogen development within the vector and halting transmission to the non-infected vertebrate host [7,8]. Most TBV candidate targets have been focused on gametocytes, gametes, zygotes or ookinetes [9]. Li et al., [10] concluded that ookinete micronemal proteins, chitinase 1 (CHT1), circumsporozoite protein/thrombos

Abstract: in addition to numerous immune factors, c-reactive protein (crp) and nitric oxide (no) are believed to be molecules of malaria immunopathology. the objective of this study was to detect crp and no inductions by agglutination latex test and griess microassay respectively in both control and malaria groups from endemic areas of iran, including southeastern (se) (sistan & balouchestan, hormozgan, kerman) and northwestern (nw) provinces (ardabil). the results indicated that crp and no are produced in all malaria endemic areas of iran. in addition, more crp and no positive cases were observed amongst malaria patients in comparison with those in control group. a variable co-association of crp/no production were detected between control and malaria groups, which depended upon the malaria endemic areas and the type of plasmodia infection. the percentage of crp/no positive cases was observed to be lower in nw compare to se region, which may be due to the different type of plasmodium in the nw (plasmodium vivax) with se area (p. vivax, plasmodium falciparum, mixed infection). the fluctuations in crp/no induction may be consistent with genetic background of patients. although, crp/no may play important role in malaria, their actual function and interaction in clinical forms of disease remains unclear.

Abstract: Background: Iran has undergone a remarkable demographic transition over the last threedecades. Socioeconomic status (SES) indicators including education, income, and occupationare associated with coronary heart disease (CHD) risk factors, morbidity, and mortality. Theaim of the present study was to describe demographic and socioeconomic characteristics, theirassociation to the diseases, and to explore the predictive risk of CHD in Tabriz, the fourthlargest city in Iran and the capital of East Azerbaijan Province.Methods: This cross-sectional descriptive study was carried out to explore and analyze thecurrent SES status of CHD patients. The study was conducted in Tabriz and all patients(n=189) refereed to the Central Referral Hospital for cardiac patients (Shahid Madani Hospital)from 2009 to 2010 were considered. A researcher structured questionnaire with 15 questionswas used to collect data. Descriptive statistics were used to describe the basic SES featuresof the CHD patients and data analysis was done using SPSS ver. 16.Results: Less educated participants were more susceptible to CHD. Regarding to occupationalstatus, housewives and retired men were in higher risk of CHD than the rest of the people.Studied patients also reported to be mostly from urban areas that were living in apartmentcomplexes.Conclusion: In line with some international research evidence the study results suggested thatpeople from lower/middle social classes were in greater CHD risk than higher social classes.This epidemic might be halted through the promotion of healthier lifestyles and the support ofenvironmental and policy changes.

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0094520
Abstract: Background The suction sockets that are commonly prescribed for transtibial amputees are believed to provide a better suspension than the pin/lock systems. Nevertheless, their effect on amputees’ gait performance has not yet been fully investigated. The main intention of this study was to understand the potential effects of the Seal-in (suction) and the Dermo (pin/lock) suspension systems on amputees’ gait performance. Methodology/Principal Findings Ten unilateral transtibial amputees participated in this prospective study, and two prostheses were fabricated for each of them. A three-dimensional motion analysis system was used to evaluate the temporal-spatial, kinematics and kinetics variables during normal walking. We also asked the participants to complete some part of Prosthesis Evaluation Questionnaire (PEQ) regarding their satisfaction and problems with both systems. The results revealed that there was more symmetry in temporal-spatial parameters between the prosthetic and sound limbs using the suction system. However, the difference between two systems was not significant (p<0.05). Evaluation of kinetic data and the subjects’ feedback showed that the participants had more confidence using the suction socket and the sockets were more fit for walking. Nevertheless, the participants had more complaints with this system due to the difficulty in donning and doffing. Conclusion It can be concluded that even though the suction socket could create better suspension, fit, and gait performance, overall satisfaction was higher with the pin/lock system due to easy donning and doffing of the prosthesis.
